Agriculture Use Black PP NonWoven Geotextile Ground Cover For Landscape And Weed Control

Geotextiles are permeable non-woven fabrics used for separation, filtration, reinforcement, protection or drainage. Geotextiles allow the filtration or separation of particulate layers in road and rail applications, films for protection in landfill applications, for coastal defense applications, and for landscaping to protect surfaces and structures from weeds and root growth.

Polypropylene geotextile is a key technical material in ballastless track railway projects.

Its application is mainly reflected in the following core areas and technical characteristics:

About the application of PP nonwoven staple fiber geotextile

Environmental protection and municipal engineering

1. Landfill and sewage treatment

·Impermeable layer: used for isolation at the bottom of domestic waste landfill to prevent the spread of pollutants.

·Filter medium: intercepts particulate matter in sewage treatment plants to ensure smooth drainage.

2. Water conservancy projects

·As a filter layer for wells and pressure relief wells, it balances the pore water pressure of the soil.

Agriculture and Landscape Engineering

1. Land Management

· Covering and Drainage: Used for covering farmland to inhibit weed growth and promote soil drainage.

· Horticultural Application: Prevent soil compaction in horticultural drainage systems.

Special engineering scenarios

1. Sports venues and airports

· As a foundation isolation layer, it enhances the bearing capacity and is suitable for the construction of sports venues and airport runways.

2. Coastal and reclamation projects

· Resist seawater erosion and is used for beach reclamation and port revetment.

Other applications

· Composite material reinforcement: combined with geogrids to improve the lateral tensile strength of the roadbed.

· Temporary rescue: used for embankment reinforcement and pipe burst prevention in flood control and rescue.

‌Material property requirements

1. Mechanical properties

• Tensile strength: longitudinal/transverse breaking strength ≥11kN/m (CRTSⅡ type lower geotextile has higher requirements).
• Burst strength: ≥4.3kN (700g/㎡ specification).
• Friction coefficient: ≤0.35 to reduce wear and extend life.

2. Durability

• Acid and alkali resistance, mildew resistance: polypropylene fiber has excellent chemical stability and is suitable for long-term exposure to concrete alkaline environment.
• Design life: 700g/㎡ polypropylene geotextile can meet the service requirements of high-speed rail for more than 70 years.

3. Construction adaptability

• Flexible specifications: single roll length ≥32m, width 2.5-2.9m, easy to lay on site.
• Thickness control: the thickness of the lower geotextile is 3.0-3.5mm, and the upper layer is 1.8-2.2mm, which can meet the needs of different structural layers.

Precautions

· Construction suggestions: It needs to be used with other materials (such as HDPE membrane) to enhance the anti-seepage effect.

· Storage requirements: Avoid humid and high temperature environments to prevent fiber degradation.
